A behavior record is not a verdict
Play, excitement and the missing part of the scene
A room can be lively before mounting begins, but "everyone was playing" can hide several different observations. It is more useful to preserve what happened before, what was seen and how the interaction ended than to assume a shared emotional state.

Excitement is one possible context
VCA and ASPCA describe mounting in response to excitement or stress. The same visible action does not distinguish those states on its own. Describe events such as a greeting, running or a change of room without declaring which feeling caused the mounting.

The other dog matters too
UC Davis notes that another animal may object and that injuries can occur. Do not treat mounting as an automatic agreement between dogs. This site does not give a body-language checklist that authorizes leaving an interaction to continue.

Do not make a demonstration for the ledger
A useful record concerns something that already happened. Do not arrange another greeting or bring dogs together to see whether the behavior repeats. If you are worried about aggression or an unsafe interruption, get qualified help rather than testing a technique from a page.

Record the ending you actually saw
You may know that one dog moved away, that a person left the room or that you did not see the end. Keep that distinction. "The interaction ended" is not the same as "both dogs relaxed," and an unknown ending cannot be filled in by a tool.
